Compiling Raspberry PI OS image entirely from source

[SatyaSri]

Hi,

Using cross-compilation host as Debian Buster with CPU architecture:i386 ,I am trying to cross-compile all the packages of Rasbian Buster OS .
I could not able to compile all the packages and seeing so many failures while cross-compiling.

Is there any source tree available to compile Rasbian Buster OS.
Can you please help me out on this.

Thanks in advance,
